Явор Шопов

On 11.11.2022, on the way to the National Forum of Speleology (Dryanovo November 11-13), of which he was the main organizer, in a car accident, we lost the speleologist, scientist, researcher and friend Associate Professor Dr. Yavor Shopov (1962 – 2022).

Yavor was active caver since 1980, when he finished caving course in “Iskar” Speleo club, Sofia, Bulgaria. Then he was active member of the club from 1981 to 1988. Yavor founded and led the University Section of Speleology at Sofia University St. “Kliment Ohridski”. He was an organizer and speaker at numerous international and national scientific forums on speleology, author of valuable scientific publications.

Some of his many achievements and responsibilities during the years included:

  • President of the Commission on Physical Chemistry and Hydrogeology of Karst of the International Union of Speleology since 1993,
